Description

  • Fiber length dependence (100, 200, 300 mm)
  • Hit position dependence (20, 40, 60, 80, 100, 150, 200 mm from MPPC)
  • Fiber speices dependence (R=0.5, 1.0, 1.5mm, L=0.5mm)
  • Light contact dependence (Air, Grease)
  • Light loss after Clear-Fiber (SQ), Wavelength shifting fiber (Y-11 SQ non-s, Y-11 SQ s type, YS-2 Round, YS-4 Round)
